IMPROVEMENT IN APPARATUS FOR THE MANUFACTURE 0]? ICE The Schedule referred to in these Letters Patent and making part of the same- To all whom it may concern:

frigerating apparatus;

Figure Etis a pian view of the same;

Figure 3 is a longitudinal vertical section of my icemaking apparatus and L Figure 4'is a plan view of the same.-

This invention relates to the manufacture of ice and refrigeration of air by means of cold produced by the vaporization of chimogeue or other volatile hydrocarbon in a vacuum, the vapor drawn off in the production of the vacuum being returned to the receptacle again in a liquefied form. The invention consists-.-.

First, in conducting an, pure or charged with vapor from the retort, by means of a straight pipe passing down through the said vapor-dome into the lower part of the chimogene-receptacle, and opening there into perfurated pipes laid along the bottom of the receptacle, through which such air escapes into the residuum of the chimogene, and stimulates the production of vapor therefrom;

Second, in placing the ice-forms in freezing-chambers made in the chimogene-receptaclw I Third, in placing between the walls of such freezing-chambers and the outside-of the ice-forms, rubber cushions, which prevent the circulation of air to and from the freezing-chambers, and wipe off water from the forms when lifted out.

In the drawings-+- B, figs. 3 and 4, is a metal receptacle for chimogene, placed, with a felt covering, 1), within a wooden case, B, and having a dome, B, projecting up from its surface, and communicating with its-interior, Through this dome the vapor rises when the air-pump is in operation, which produces in the dome the same degree of cold that prevails in the receptacle.

The pipe 0 conducts the air and vapor into'the vesscl C, which is filled with water, through which the pipe passes in a coil, cooling the water, the latter be ing then drawn off into the ice-forms 1). The pipe 6 thence runswto the pump-barrel 1), opening into the latter by a valve.

A pipe, 0', opens out of the pump-barrel, and conveys the vapor to the condenser D, whence it runs in liquid form to the retort E. Out of the retort the liquid is forced, under pressure, through the filter E by the pipe e", the latter running the whole length of the dome B", and the liquid there being cooled previous to its reintroduction to the receptacle. Such cooling, thus effected, constitutes one of the important features of my invention. I

The ice-forms D have flanges on their upper ends, by means of which theyare hung in freezing-chambers D, made with open-upper ends in the receptacle, but impervious to the chimogenc. Said chambers contain freezing-baths, kept at the-proper temperature by their situation, and speedily convert the water in the forms into ice. The same effect is produced if no bath be employed.

Rubber pachings, 72;are secured onthe top'cf the receptacle, around the mouths of the freezing-chambers in position, such'that they support the flanges of the ice-forms, and prevent the access of air to the freezing-chamber. They also serve as wipers when the forms are taken out, and prevent the dripping of one form into another.

A pipe, h, opening from the top of the retort E, runs to the top of the vapor-dome B" and down. through the same to near the bottom, of the receptacle, 'where it communicates witha series of perfeiated horizontal pipes, h h ,which admits the gaseous air from the retort to the residuum of the hydrocarbon settled at the bottom of the receptacle, which, when at a low temperature, is nearly non-productive of vapor. The aircurrents agitate the mass, extracting the vapors therefrom and carrying them up,- i n' .company with the bubbles. The passage of the air'through the vapor-dome suitably coolsit. I

A, figs. 1 and 2, is supposed to represent a room in a house, or on ship-board, 'or a car. To the sides of the room, and near its top, are attached, in any suita ble manner, hollow metal cases, a a, of any required dimensions, which are to be partially filled with chimogene. I

The cases care connected by a pipe, a, from which a branch, a", leads on" to the pump.

The metal cases are transpiereed by a number of apertures, a, for the passage of air.

On the exhaustion of-the air in the cases by the action of the pumps, the chimogene becomes vaporized,

as' before described, and an intense degree of cold is produced in the cases; Naturally, therefore, the air.

in the transverse passages of" becomes cooled, and falls to the bottom of the room, and acirculation takes place which equally cools every portion of. the apartment.

The supply of chimogene'iu the cases is maintained in the same manner as in the "receptacle B and the residuum similarly disposed of.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

v 1. The combination of removable ice-forms D with fixed freezing-chambers D, when the latter are made in the receptacle B, the arrangement being as set forth.

-2. The rubber packing and wipers h placed around the mouths of the freezing-chambers, substantially as and for the function specified.

3. The method of agitating and vaporizing the hydrocarbon residuum by the introduction of air or gas to the same by means of perforated pipes h" h, substantially as explained.

To the above specification of .my improvement I have set my hand this 23d day of September, 1869.
